For accessing the menu respectively the properties of the graphs there are icons in the upper right corner:

Snapshots

The Analyzer offers the possibility to take snapshots of frequency over time graphs (depending on your device up to 14). A snapshot is created if you start a Leq measurement, press the hold button or the snapshot button. Each snapshot has its own bar / line graph, an icon (which represents a live updating miniature of its corresponding graph) and it’s unique color. Touch the icon to save, export, clone, change color or remove the corresponding snapshot.

Workspace

The workspace is the summary of all snapshots and the actual graph. Touch the workspace icon and save the whole workspace (including color settings), export it, change the background color or remove it for clearing the display.

Save & export

Each snapshot and even whole workspaces can be saved in the Analyzers own proprietary data format. All records are listed in the menu under records. They can be loaded, shared via email or iCloud and exported to images (.png) or text files (.csv). When exporting a workspace to a png file all graph and background colors are preserved while the export of a snapshot creates a black on white picture.

Menu

Use thecog wheel in the upper right corner to access the menu. Here you can manage your records, change various settings, visit the store or make use of the sophisticated in-app help.

Records

The left column shows your records. If you select a record a preview appears in the right column. It is zoomable like your main view. If you push the load button the graph shows in your main view. You can delete it, export it to .png or .csv files, send it via mail or move it between local storage (on your iDevice) or iCloud if activated. You can open and share .png and .csv files in appropriate Apps like FileBrowser or Dropbox.

iCloud

If you want your records available on all your devices you can activate iCloud storage. Go to the iDevice settings -> Analyzer and turn iCloud to on. Now you can move your records between local storage and iCloud storage using the export function!

Audio IO settings

The Analyzer uses either the built-in microphone, an audio source attached to the headset input jack or any suitable USB class-compliant audio hardware attached via the dock connector. The iOS automatically detects which audio input and output are used. If the audio IO route changes the Analyzer automatically blends in the current audio route.

You can select input and output routing in this menu.

When a class-compliant USB audio interface is attached the Analyzer will work always on channel 1&2, 3-8 are not accessible at the moment. We tested successfully and can recommend: Apogee’s One, Duet and Quartet, the RME Fireface UCX, the Alesis IO dock and the Midiface Audioface II.

Analyzer

The frequency range defines the maximum range of the frequency (horizontal) axis.

A single band can either show the sum of energies of each FFT point between left and right border of the band (summed energy) or the mean over the whole band. This decision is made with the band filter mode setting. In sum mode a pink noise input shows a horizontal line and a white noise input shows a line with 3dB / octave rise. In average mode a pink noise input shows a 3dB / octave drop and a white noise input shows a horizontal line:

It is possible to view a normalized spectrum. If the normalization is activated, the level in the frequency view is always normalized to full scale.

The dB range defines the maximum range (dB) of the vertical axis. It is of course only available when normalization is deactivated.

The block size defines the length of the analysis interval.

With the reference frequency you define the “middle” of the frequency scale. Very common for measurements is 1000Hz. We added 440Hz also because this is the “musical” reference (A4).

Here’s how you can do it easily: touch the workspace icon in the right upper corner, select caption -> peaks. Now you see lines: the vertical lines show the 3 most prominent frequency peaks (the one with the highest level is the one you’re looking for), the horizontal lines show the corresponding levels.

I downloaded a while ago Analyzer and purchased an I436 micW mic.
when i installed this special callibrated feature i need to give there a number from my callibrated i436. which is on the manual .
this is 5.6mV/Pa.

My question is ; Is this correct to give 5.6mV/Pa ?,, as i gor a quite low input on the mic . Less even as on my ipad 4 int.mic .

I’ve bought the analyzer app and for the most part I’m very pleased with it. There is a couple of issues I would like to address. First of all, it seems that the response button in analyzer mode doesn’t really do anything? Or maybe it’s just that the frame rate of the bars is to low but the result is that it’s difficult to get a good average. The competition analyzer app from onyx3 seems to get it right but lacks many other vital functions.
Another thing I would like would be to change the overall color scheme of the app.
Other than that it a really great app that I use every week. 🙂

The Analyzer is a combination of SPL Meter and frequency analyzer. The Response button is for selecting the IEC conform SPL Meter response times and don’t affect the frequency display. But we got the idea… Maybe there will be a settings option for adjusting the response of the frequency graphics in a future version.
We already made the background colors and graph colors user adjustable – so there are only the buttons (which will stay as they are), the font color (we will think about it) and the grid color left… We take this into account when discussing the next improvements!

Can you suggest a good program settings for most performance to mesure a PA System, I mean ( weighting ? ; bandwidth? scale? band filter mode?and window funtion -i mean best settings of this!
Best regards Martin

you should first turn off weighting because this applies the weighting filter curves from SPL measurement to the spectrum. If you’re using pink noise for measurement you should use bandfilter mode “summed”, with white noise “average” – both means you’re seeing a horizontal line as a flat frequency response. If you don’t care about levels and want to compare different snapshots / curves it’s great to use the normalized view – if absolute levels are important you should deactivate normalization. For detecting feedback we built in an automatic peak detector. You can activate it in the frequency view by touching the workspace icon and setting caption to”peaks”. As for the window function: they all work well, Blackman or Blackman Harris are great for mixed signals, flat top is perfect for sinusoidal signals.

Hello Jose,
we apologise for your trouble! If you want your money back just ask iTunes for it they will do it of course BUT: if you wait a few days the update which fixes this bad behaviour will be available – it’s already in review at iTunes.

sorry for this! We are aware of this problem and are already working on a solution. The Analyzer has an incompatibility with iOS 5.1.x which will be fixed in the next update. We apologise for the trouble! Hopefully the fix will be released within the next few weeks!

sorry for your trouble – of course you can get your money back! Just ask iTunes for refund and you’ll get it. But: The problem with iOS 5.1.1 will definitely be fixed in the next update (v2.3.2) which is already in review at iTunes – hopefully it’s out there in a few days!

I bought this app with the MicW i436 correction for my iphone and it is working great. Now I would also like to use it on my new ipad air with the same Apple-ID. It was no problem using the analyzer without buying the app again, however, the MicW i436 correction is not active on the ipad. Do I have to buy it again for the ipad?

Hi, I want to use Analyser with MICW i436 and measure true SPL levels. I have purchased i436 correction app also. Sensitivity indication in i436 manual is 43.1 mV/Pa. However, I can set mis sensitivity only from 3 mV/Pa to 11 mV/Pa in Analyser micW i436 setting. Please suggest how I can set correct value?

Hello Andres,
we found the reason for those mysterious values: it is a human mistake… 🙂
The guy who made the test in the factory wrote down not the transfer factor (mv/Pa) which the App requires but the sensitivity (dB). Your value corresponds to “sensitivity” of 7.0 mv/Pa which is the value you need for Analyzer calibration.

Hello. Sorry, me again. After restarting the iPhone 5s, it worked. Then I switched to a different audio app (Shazam) to detect a song. Switched out of that and back to your analyzer, it stopped working. It seems I’ve got to restart my iPhone every time I want to use this app?

this is strange. Concerning audio input the Analyzer should behave as any other App, catching the input stream from the iOS when put to front. It is possible though that other Apps use background audio preventing the Analyzer to get access to the microphone while they are running in background. If the problem continues please make sure to turn off other audio apps (double click the home button and swipe them upwards). And please make sure the Analyzer has access to the microphone (settings -> privacy -> microphone ).

I’m considering purchasing your app for studio use because my Samson D-1500 has been damaged beyond repair and I like to have a device for analysis that isn’t just another floating window in my DAW. Would I be able to use your product in this way? If so what would be the most cost effective, yet suitable method of connecting 1/4″ line level outputs to an iPad 2 for use with your app?

need to always change the color of a clone after cloning hold-peaks to compare front mix with monitoring at live gig. It changes the color of the original too…could you implement that you can change the color of a clone without changing color of original?

unfortunately there’s a problem with ANalyzer 2.3.3 and iOS 5.1.1. We could not forsee this because all testing went well, but the version in the iTunes Store is not ok. Anyway, we worked hard on fixing this and a new version 2.3.4 is already in review at iTunes and will hopefully be available in a few days.

If you have a backup you could maybe go back to the previous version…??

If not I’m afraid you’ll have to wait a few days for the update. We apologise for the trouble!

I am in the process of building a high end car stereo, I am going to be running an active 3-way front stage. Each speaker will have its own amp which will be crossed over using a DSP-Moaconi 6to8 (http://www.mosconi-system.it/product/gladen-dsp-6to8/)
Tuning the system is going to be a long process… I have a friend that is suggesting that I get an RTA and equipment to help me tune my system. He asked me to look at:
TrueRTAhttp://www.trueaudio.com/index.htm
System 3 – $236.92
1/24th Octave RTA
I have looked at your Analizer app along with the i436 Omni Measurement Mic & i436 Kit Package

How do the two compair and what features would stand out. To me they both look like real good systems. Could you help me out deciding which would be the better one to help me tune my car stereo.
Thank you, Coolcountry

of course both work fine. But: The Analyzer is much more “mobile” and miniature because it’s working on iPad and iPhone. TrueRTA is a great software. Along with laptop and audio interface and measurement microphone it is a lot of equipment though. True RTA offers a sweep, which analyzer does not at the moment. Analyzer has much more detailed Graphics and resolution far beyond TrueRTA. So it’s your choice in the end – may be both?

The most recent update – April 9th, has complely broken calibration. Yes I can still calibrate it but it after updating everything shows up about 10db higher than before. I can no longer trust the accuracy of the app. I am using the built-in mic and have calibrated it before with a calibrator. I know it’s not a great mic so it’s not perfect, but if was close-within a few db. Now it is way off. Any idea why this may have happened? Or a way to restore this without having to have the calibration set to -12db? Before it was -2.4. Even at -12 if doesn’t seem as condistent as before….

we apologise – again!!! There’s an issue with the new 64bit stuff Apple requires now which unfortunately causes much (non-expected) trouble when running Analyzer on iOS 5.1. As all our test versions worked fine on iOS5.1, we are very frustrated with this but: we are working hard to solve this issue – please be patient for another few days.

Hello Daniel.
The microphone is activated. I think this is not the problem.
The app only run in my ipad if i open after restart the ipad, but the second time i try to open the app not work any more until i restart again the ipad.
Allso the noise generator not work.
The app take more time than normal to open when not work.

Can you please advise about 2 things:
1. a class 1 mic which works with Analyzer
2. a compliant audio interface (preferably 4 inputs) which works with iPad mini retina display. I know Alesis has the new iO Mix with 4 channels input, but it apparently only docks an iPad standard size, not a mini retina
Thanks in advance
Mick

Hi,
I e-mailed my test.dspgraph from my iPhone 5s to my Lenovo PC, however ‘this file cannot be previewed because there is no previewer installed for it’.
Which ‘previewer’ would you reccomend me to install in order to view dspgraph files correctly?
Thank you, and best regards,
Mitja.

hi,
it would be convenient if your software displays the actual value corresponding to the frequency whose level is the highest.
just above this frequency, for example.
this would allow a bit more readable.
could you do this?
best.

Works perfectly on my iPad, but have a problem on my iPhone (unfortunately replied ‘no’ when asked to allow access to the microphone at first start up) : I cannot see any signal, and I know I should make sure the Analyzer has access to the microphone: settings->privacy->microphone, but I cannot access “privacy” in the settings meny (not even when scrolling). Could you please tell me how to access ‘privacy’?
Thanks!

I very fine app with good functionality.
Question:
1. I really need a function for ON / OFF to “freeze” the testresult before export.
2. I also would like the signal sweep function – integrated like TrueRTA. Will such a function be availible in hte future?
/Frede

One more thing…………….
The export file (CSV) is a big problem for me.
Because importing in Excel 2010 where we in my country use
(,) as decimal sep. and not (.) everything is mixed up.
Could you give us the possiblility og choosen decimal sep. ?

there are sometimes issues with iOS and the Audiobus engine. Please try the following:
– quit the Analyzer and all other audio apps by double pressing home button and up swipe.
– go to settings -> Analyzer -> privacy -> microphone -> and turn allowance off.
– start Analyzer again and quit it again.
– turn allowance for microphone use on again.
– restart the Analyzer

It seems a little complicated and stupid but it actually worked on my own 5S – since this procedure it’s running perfectly on it.

I just installed Analyzer on my new iPhone 6 and on my old iPhone 4. I use the SPL meter to measurement the Leq. The value measured by the iPhone 6 is 12 dB lower than the value measured by the iPhone 4. I believe that all settings are the same on both iPhones. Is it normal to have such a difference ?

I would like to use your app (which I have already purchased) for analyzing a very low noise in the frequenzy range beween 20 an 80 Hz. Which of the microphones that are compatible with your app and that you are offering frequenzy compensation for would you recommend for this purpose?

Have verified microphone setting enabled in Settings but still getting no input. Also have dB Volume on same device. With same settings works fine. Any ideas? Also have no generator output with speaker enabled.

Thank you for dropping support on the iPhone 5c. It is the iPhone I have been using for a year now and have been very pleased with how the program worked on it. Since I paid for the program and now you have decided to no longer support its use on the iPhone 5c I should be seeing my refund for the obsolete use of the program by the end of next week?
